You will develop, document, and verify Python-based solutions.

Responsibilities

• Design original computational STEM problems that simulate real scientific workflows.


• Create problems requiring Python programming to solve.


• Ensure problems are computationally intensive, unsolvable manually within reasonable timeframes (days/weeks).


• Develop problems requiring non‑trivial reasoning chains and creative problem‑solving approaches.


• Verify solutions using Python with standard libraries (numpy, pandas, scipy, sklearn).


• Document problem statements clearly and provide verified correct answers.

Requirements

• Master's or PhD in Computer Science, Mathematics, Physics, Engineering, or related STEM field.


• At least 5 years of Machine Learning experience with proven business impact.


• Strong programming skills in Python (numpy, pandas, scipy, sklearn).


• Solid understanding of numerical methods and computational algorithms.


• Research or industry experience involving computational problem‑solving.


• Advanced English proficiency (C1) or above.


• Ready to learn new methods, switch between tasks quickly, and work with challenging guidelines.

Benefits

• Paid per expertise; rates up to $32/hour depending on skill, experience, and project needs.


• Part‑time, remote freelance project that fits around your primary commitments.


• Work on advanced AI projects, enhancing your portfolio.


• Influence how future AI models understand and communicate in your field of expertise.


• Applications will be considered on a rolling basis.


• Refer a colleague to double your chances of interview.
